Look into a sulfur burner.
Add thumb for sulfur burner. Outside only. I have used this on outside crops and recently did my tent outside. When used on outside crops it leaves a residue on plants that zero bugs can stand. Great till the next rain.
This is the nuclear option for pest and pathogen control.

No they can be used safely indoor no need to burn outdoors just use the powder to dust plants I would never use any kind of sulfur on plants indoor but bombing rooms in-between grows is fine an safe to do.

I just lost a beautiful plant because I had to go out of town for three days and when I got back it was covered with PM. Chopped it and tossed it. I hosed the entire grow tent down with H2O2 3%, 1.25 bottles in almost two gallons of water. I feel your pain.

Micronised sulphur isn't the same as burning sulphur, burning sulphur produces sulphur dioxide gas that's deadly to insects.

Permethrin smoke bombs are another option Permethrin kills eggs and adults and they're cheap circa $4 and ready to burn.
